That was the first official 3x3 tournament so a lot of people still don't know about it .

Yes pro players are allowed . France sent pro players and I think Greece sent pro players but under the age of 23 or something like that . Spain sent some ex pro players like Garbahosa and Jimenez ( although he signed one month contract with Euroleague team Unicaja Malaga after a couple of months ) . I don't know if someone else sent pro players but it's interesting that team without pro players won the gold .

A bunch of teams did. But I seriously doubt the NBA would ever agree to it.

And none of the other main national teams will either. Greece's federation president said he only let some under-23 players play there because it was the first tournament and they were hosting it.

He said in an Olympics tournament no one from the senior team would play in it.
